Jose Mourinho seemingly continued his war of words with Arsenal boss Arsene Wenger last night.
As reported by Sky Sports, the Portuguese tactician appeared to take a dig at the Gunners chief as he labelled the match official "weak and naive" for failing to give a penalty to his side during their Champions League contest against Dynamo Kiev.
The referee refused the Blues a spot kick following a challenge from Serhiy Rybalka on Spain international Cesc Fabregas.

The Blues failed to secure all three points in Ukraine, leaving themselves with work to do ahead of the final three games in the group. But, in his post-match interview, Mourinho opted to take to take a subtle dig at rival Wenger.
Wenger previously labelled Mike Dean as "naive" and "weak" after Arsenal were beaten at the hands of Mourinho's side in west London earlier this season.
Mourinho, on the other hand, was recently fined £50,000 by the Football Association for suggesting officials were 'afraid' to hand his team penalties. Ultimately, after last night's contest, the self-proclaimed 'Special One' took it upon himself to mirror his rival's comments.
The Chelsea boss stated: "The word 'afraid' is a punishment, and a hard punishment. But to say the referee was 'weak and naive', referring to one of the top referees, not just in this country, also in Europe, to call him 'weak and naive' we can do."
Let's be honest, luck was against Mourinho and Co. last night as they failed to secure all three points in Europe's elite competition. Twice hitting the woodwork and failing in their protests for a penalty proves things just aren't going the club's way right now.
